Agent: Redskins signing CB Williams to upgrade secondary

WASHINGTON (AP) Cornerback Cary Williams has signed with the NFC East champion Washington Redskins ahead of their wild-card game against the Green Bay Packers, taking the roster spot of safety Kyshoen Jarrett, who heads to injured reserve.

The addition of Williams, released by the Seattle Seahawks last month, and loss of Jarrett were part of a series of moves announced by the Redskins on Tuesday.

Center Kory Lichtensteiger was activated off IR after missing the second half of the regular season with a neck injury; he is expected to reclaim his starting job from fill-in Josh LeRibeus. Backup center Brian de la Puente was waived.

The Redskins also released linebacker Derrick Mathews from the practice squad and signed cornerback Al Louis-Jean to the practice squad.

The 31-year-old Williams had 46 tackles in 10 games with Seattle this season. The Redskins are Williams' fifth NFL team since he entered the league in 2008.

Washington is coping with injuries to its already depleted secondary, including two in the regular-season finale Sunday in Dallas.

While cornerback Dashaun Phillips could play against Green Bay despite what coach Jay Gruden said ''looks like a stinger,'' Jarrett already had been ruled out for the playoffs because of a nerve issue affecting his right arm.
